Fan Silencers

A wide variety of fans are used in today's industrial facilities. The noise generated by fans can quickly become an issue in these environments, necessitating the use of fan silencer. SysTech will work with you to consider a variety of factors in addressing your specific fan needs and facility requirements including issues such as:

• Space restrictions
• Maintaining air flow by minimizing pressure loss thru the silencer
• Meeting environmental noise regulations and industrial health and safety requirements
• Materials of construction specific to application
• Accessories including rain hoods, transitions, support brackets and flow measuring devices

Many industrial applications require inlet and outlet fan silencers in order to comply with OSHA standards as well as local noise ordinances. Ongoing exposure requires environments of no more than 90 dBA to avoid hearing damage, while conversation requires 80 dBA or less.

SysTech offers a variety of fan silencers and noise reduction methods to meet every application need including:

• Absorptive or Dissipative Silencers – use sound absorbing material to attenuate sound waves
• Reactive Silencers and Mufflers – system reflects sound waves back to the source
• High Pressure Vent and Blowdown Silencers – utilize heavy duty perforated diffusers preventing the generation of low frequency noise
